To all whom it may concern.'

Be it known that I, JOHN R. BUTLER, a

` citizen of the United States, residing at the construction of Valves of this characterwhereby the pumping ott water and other liquids will be materially'facilitated.

With these and other objects in view, the invention consists of the novel features of construction, combination and arrangement of parts hereinafter fully described andl claimed and illustrated in the accompanying drawings, in whiche- Figure 1 is a perspective view of the device, the valve box or casing being partly broken away to disclose the interior construction, and Fig. 2 is a vertical longitudinal section; Fig. 3 is a horizontal section showing my improved valve connected to the cylinders of a current pump.

Referring more particularly to the drawing 5 indicates the valve box or casing in each end of which the openin s 6 are formed. It will be noted that four o such openings are provided in each end of the casing. Two of these openings, however are plugged while two of the pump cylin ers are connected to the other pairof openings. The plugged openings are provided for the purpose of allowing easy access to the end chambers so that they may be cleaned to permit of making yrepairs to the valves which connect said chambers with the lower central chamber, as will be hereinafter more fully described. The drawing discloses a valve which is adapted for use in connection with a four cylinder pump engine, two of the pump cylinders being connected to each end of the valve casing.

The top and bottom of the casing 7 and 8 respectively are connected by the integral walls 9. These Walls divide the interior of Specication of Letters Patent.

the casing into 3 compartments and am equally spaced from each other and from the ends of the casing. The walls 9 are in turn centrall` connected by a horizontal wall 10 which provides the upper and lower chambers 10'.. rlhe walls 9 are also centrally connected to the ends of the casin b a vertical wall 11 which divides each O t e end compartments into two separate chambers 11. Thus it will be seen that six separate chambers are formed each of the same capacity, the end chambers having their greatest dimension vertically positioned while the central chambers are disposed at right anglesto the end chambers and have their greatest dimension transversely positioned. Openings 12 are formed through one sideof the casing 5 and communicate with the central chambers 10. To the 'upper opening 12 the inlet pipe is adapted to be connected while a suitable discharge pipe is connected to the lowermost opening. lPorts 13 .are formed in the walls 9 and afford 'communication between the central chambers and the end chambers. These valves 14.

The check valves each comprise a cylindrical casing or Wall 15 and a. valve plate 16. Thisvalve plate carries an arm 17 upon the end of which transverse trunnions 18 are formed. These trunnions are each formed may beinserted into the slots or -recesses 19 of t-he ears 19 which are formed upon the top of the casing 15 as clearly shown in Fig. 1. The valves which open communication bechambers are outwardly positioned or in other words they protrudel into the end chambers. The remaining valves, however, which aii'ord communications between the end chambers and the lower central chamber are positioned entirely within the latter and the valve plates thereof open inwardly. There are four of these valves which open communication between each of tlie end chambers and each of the central chambers, thus necessitating the employment of eight separate valves.

InFig. 3 of the drawings I haveillustrated my improved valve connected to the cylinders of a current pump. This pump forms no part of the present invention as its i construction comprises the subject matter of tween the upper central chamber and theend ports are normally closed by the check with a Hattened surface 18 whereby they l l E' fixed upon the shaft S which is drivenl trom any Suitable source of power` supply.

Pipes pare connected to the upper openings 6 in the end of the valve casing and to the piston cylinders C. T he water, in the action of the engine is constantly moved back and forth through the pipes p, in the reciprocation of the en ine pistons l?, between the end chambers-o the valve and the pump cylinders.

In the operation of the device, clear water is poured into the pump cylinders before the engine is started. VUpon the reciprocation of the pump pistons, the water being umped will be drawn into the upper or inlet chamber, and will impinge upon the valve plates 16 of the upper check valves 1.5 and open them outwardly, the water flowing into. each of the end chambers 1l. F rom these chambers the water discharges into the lowermost chamber 10', opening the valve plates of the lower valves inwardl From this chamber the water is finally discharged through the -outlet pipe which is communicating therewith through the opening in the side wall of the casing 5. By providing the pump cylinders with clear water, upon thev operation of the pistons this water will be moved backward and forward between the cylinders and the valve following the movement of the pistons. The, eater part of the sediment contained in t e water is deposited in the various chambers ofthe valve case in its passage through the same, and the clear water in the pump cylinders is adapted to be periodically renewed so that the sand, gravel and other sedimentary matter which finds its way into the pump cylinders 'will be insignificant.`

By the use of my improved valve, the lperiod of use -of the pump cylinders is' greatly prolonged and a hlgh percentage of eiiciency constantly maintained.

The Vcasingkii is provided with a number of hand holes 20 4in the sides and top and bottom thereof, so that re'ady access may be l valve will be rea ily understood without nev cessitatinga more extended description,

The devlce is simple, may be manufactured at a minimum cost and is very reliable,

etlicient and durable in use.

While I have shown and specically set forth the preferred form of my invention, -it'will of course be understood that the same is susceptible of numerous minor modifications without departing from the essential features or sacricing any of the advantages thereof. v

Having thus described the invention what is claimed is Tim c ombination with a current pump including cylinders arranged in pairs and each having a reciprocatory piston'therein, of a valve comprising a rectangular casing, ver'- tical transverse walls arranged in spaced relation to the ends of thecasing, longitudinal walls connecting theends of the casing to said vertical walls and dividing each end of the casing into separate chambers, a horizontal wall 'integrally connecting said ver tical transverse wa'lls and the opposite side walls ofthe case to provide upper and'lower central chambers, one` of the side walls of the casing having inlet and discharge ports communicating with said upper vand lower l chambers respectively, said vertical transverse walls having openings thereln aordmg communication of each of the central chambers with each of the end chambers,`

valves mounted upon said walls and normally closing communication between the upper central chamber and-the" end chambers, a second setof valves normally clos-.

ing communication between the lower central' chamber and the end chambers, and pipes connecting each pair of pump 'cylinf ders to one end of 'the Valve, casing adjacent to the top thereof and opposite thev first mentioned set of valves, said pipes aiording communication between the vrespective end chambers and the pump cylinders.
